We investigated the effects of seed moisture content and storage temperature on seed germination. Seed dormancy and storage behavior of three coastal forest species, native to Taiwan, were also examined. We found seeds of Litsea garciae, Diospyros philippensis, and Myristica ceylanica var. cagayanensis did not have dormancy and most of them were able to germinate completely within 2~4 weeks under alternating temperatures of 30/20℃ with 8 hours of light. In addition, freshly mature seeds of L. garciae, D. philippensis, and M. ceylanica var. cagayanensis were similar to other large-size seed species. They were extremely sensitive to desiccation and would lose their viability as temperature below 4℃. They totally lost viability as dried to moisture contents of 33.6%, 32.0%, and 27.0% (on FW basis), respectively. When stored at 4℃ with moist sphagnum, the maximum longevity of these three species was 30, 28 and 7 days, respectively. The seeds of these three species were confirmed as exhibiting tropical recalcitrant storage behavior in our study. Based on above findings, we suggest that these tropical recalcitrant seeds should be sowed immediately instead of stored after depulped.
